From 0508c1ad0f264a24c4643701823a45f6c9bd8146 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 19 May 2021 14:16:57 +0000 Subject: erofs: fix error return code in erofs_read_superblock() 'ret' will be overwritten to 0 if erofs_sb_has_sb_chksum() return true, thus 0 will return in some error handling cases. Fix to return negative error code -EINVAL instead of 0.
